SPEGIFICATION forming part of Letters Patent No. 398,993, cat-ed. Ili'arch 5, 1889.

Application filed eptcmhcr 25, 1888i Serial 110,286,389. No modcld To all llhO/lb it may 13077.0(1'1/ 3e it known that I, \YILLIAM J. Winona, residing at ((n'merslown, in the county of Venai'igo and State of .lennsylvania,have invented certain new and useful lnun-ovements in Stave Joint-ing and Planing .llachines, of which the follmving is a s 'iccitication.

My in vent-ion has for its object to provide a stave-making machine wherein the billet passes through the various stages necessary to complete the stave, and, as it progresses, automaticz'illy controls and sets the cutting devices so as out both the bevel and form the bilge of the stave in exact proportion in relation t.) the width of the billet.

To this end my invention consists of certain novel combinations and arrangements of mechanical devices, will be hereinafter fully described, and be particularly pointed out in the claims, reference being had to the accompanying drawings, in which- Figure I is a top plan view of my machine.

Fig. is a vertical longitudinal section thereof, taken on the line 2 2, Fig. 1. Fig. 2* is a-similar view of the central portion of the machine. Fig. 3 is a transverse section of the same, taken on the line 3 5,Fig.1. Fig. l a similar view of the same on the line -i i, Fig. 1. Fig. 5 is a detail perspective view of ,one of the headblocl; devices and its operative connection with the main portion of the machine. Fig. (3 is a detail perspective view of a portion of the headblock J and its adjustable connection with the arm I. Fig. 7 is a detail view of the upper bearing of one of the cutter-shafts. Fig. 8 is a detail plan view of the swinging frame M, pivoted arms Q Q, and the diagonal disks P P; and Fig. 9 is a longitudinal section of one of the head-blocks.

I shall first proceed to describe in a general way the main features of my invention, the operation thereof, and then specifically point out and describe the different parts in detail and point out their operative connection with i are caused to operate in a peculiar manner each other.

In the practical construction of my improvement I support in the top of the main f frame of the machine a series of feedrollers l which maybe suitably connected with and i operated by the driving-gear mechanism.

These rollers are so arranged in relation to the bed of the machine that one set-t-he1ower will be disposed with their upper peripheral surfaces slightly above said bed, while the upper set. will haven yielding boa ring in th 0 frame and be arranged above the lower set. Near the forward or receiving end of the machine are arranged the trimmlug-saws, which are adj usta bly con nccied to the frame and adapted to be adjusted to or from each other to adapt them to form stavcs of greater or less width, which saws operate to trim the uneven edges of the staves. A tripping device is arranged in the bed of the machine between the sawsgvhich arranged to be operated by the moving billet in such a manner as to close the billetentrance to said saws, and thereby prevent the insertion of a second billet before the saws have completely operated upon a preceding billct.

The forward upper portions of the frame an d the feed-rolls are so constructed as to permit of the ready discharge to the sides of the machine of the waste st-uif which is cut from the billet by the trimming saws. The billetafter leaving the trimmer-saws passes along through several feed-rolls until it enters between a series of vertical guide-ro1lers arranged about centrally of the machine, which have a peculiar connection with two rockshafts journaled in the main frame beneath the said bed. The billet or stave passing between the verti 'al rollers forces them apart, which movement rotates the rock-shafts to a certain degree, which rock-shafts also have a novel connect-ion with movable head-blocks, to which head-blocks are journaled the upper ends of the cutter-disk shafts, the lower ends,

of the same being pivotally journaled in the frame. The lower ends of the shafts upon which the vertical rollers are mounted are journaled in the frame and said shafts are rotated by a belt driven from the drivingpulley.

Certain automatically-cperated mechanism is connected with the head-blocks, all of which through the medium of the stave-billet operating upon the vertical rollers and the rock shafts and a yielding roller, X, supported above and adjacent to the rear set of the vertical rollers, whereby the cuttendisks are so moved inwardly and outwardly in relation to the moving billet, and whereby the said cntters will accurately cut the bevel and form the bilge of the stave, said automatic movement of the cutters being adapted to operate upon billets of different widths. The billet after leaving the cutters passes through succeeding feed-rollers to a planing-cylinder,

which finishes the outer or convex side of the stave, from whence it passes out of the machine.

Having thus generally outlined the construction of the" machine, I will now proceed to describe each part in detail and point out its operation. To make such description as clear as possible, I shall begin it at that part of the machine where the billet is first e11- tered and describe the succeet'ling parts as near as possible during the course of the travel of said billet.

In the accompanying drawings, A A denote the main frame of the machine, which supports the table B, the forward portion of which is sloping from the center to its sides, as at b I), while its remaining portion has a curvilinear form, as at b, the table being so formed as to permit of the ready discharge of the chips, splinters, dust, &c., to the sides of the machine. Below the table and projecting through proper openings formed in a central line therein are a series of feed-rollers, a ,l1aving flat peripheral faces mounted upon shafts a, which have bearings in the beams a of the frame A.

Arranged immediately above each of the rollers a and m'ounted upon shafts 19 having yielding bearings in the frame above the table B, are a series of concave-faced rollers, U,

which are preferably twice as long as the rollers a. To the forward end of the frame A is arranged the feed-platform A, which is provided with a series of guide-1narks,1 l, to assist the operator in properly guiding the billets to the first set of feed rollers. To the front end of the machine,preferablybetween the first and second set of feed-rollers, a transverse shaft, c, is journaled in the sides of the frame above the table, and upon which shaft are mounted the trimmer-saws C. These saws are arranged one to each side of the central part of the table and are adapted to slide to and from each other upon said shaft. adjustment of the saws is accomplished by a lever, 2 2, pivoted to the frame, as at 3,which is connected to toggle-arms 4 4, which are pivoted to longitudinal arms 5 5, pivoted at their rear ends to the frame at 6 6, while their other ends are connected to collars or hubs 0, formed on the 'saws 0. Thus it will be seen that the saws may be readily thrown to or from each other by operating the handle-bar 7, and thus adapt the saws to trim billets of different widths. Arranged in an opening, (I, in the bed B between the saws C is a swinging stop, D. This stop consists of a springplate pivoted at the rear of its center, as at d, and is provided with an upwardly-projecting lip, 61 at its front end, the upper edge of which normally is flush with the table 13, and

This

the first billet passes the lip (Z which allows the plate D to drop into its normal position. This operation also times the billets properly and prevents their crowding each other at the cutter-heads hereinafter referred to. The billet after leaving the saws is fed forward and enters between a series of vertical guide-rollers, E E E E, mounted upon the upper ends of vertical shafts E E the lower ends of which are journaled in pivotal bearing-boxes e e, mounted in the main frame. Near the upper ends of said shafts E they are provided with laterally-extending rods E E which project through openings in the side bars of the frame. v

The shafts E are each provided with a s1: rocl et-wheel, 6 which are connected by a sprocket-chaime", as shown.

The speed of the rollers E E and the shafts E is governed by the speed of the passing billet. Y

To each of the rods E E are connected the upper ends of stout spring-bars F F, the lower ends of which are fixed upon rock-shafts G G, mounted in the frame.

It will be observed that the vertical rollers are formed in setstwo to eachside of the machineeach set and its connections adapted to operate one of the cutter-disks, and as their operation and construction are similar I shall only describe one set and its connections with the disk it operates.

Between the side beams, A of the frame and the connection of bars F, I arrange a coiled spring, H, upon the rods E which will press the rollers E E back' to their normal position when the pressure exerted by the stavebillet is released therefrom. Upon one end of the rock-shaft G is secured the lower end of an arm, I, the upper end of which is adj ustably connected to the uppcrsectiom. of the movable cutter-head block J, which automatically presses the cutter-disk to or from the stave-billet. I

By reference to Fig. 6 the adjustable connection of the said arm is clearly shown, the

same consisting of a cross-bar, i, mounted near the end of the bar I, which bar 2 travels upon small vertical screw-rods secured to the section J, and which bar may be adjusted upon such rods by the jam-nuts i 2 The head-block J which is shown in detail in Fig. 9, is arranged transversely in the frame, and is formed of the upper and lower sections, J the upper section arranged between slideways in the frame. 4

Arranged in front of the head-block J is them.

the cutter-disk shaft L, the lower end of which has a pivotal bearing, Z, in the frame, while its upper end is journaled in a pivotal hearing, 1, (see Fig. 7,) in an arm,Z extended upwardly from the inner end, j, of the section J. The cutter-disk shaft is also provided with a pulley, Z", over which the driving-belt passes. The lower face of the upper section is provided with a series of fine rack-teeth, 7' the purpose of which will presently appear. By this construction it will be seen that when the billet enters between the rollers E E E E it forces them apart, which movement of the rollers E E causes the rod E to press the spring-arms F outward and partially rock the shaft G, which movement of the shaft will, through the arm I, move the section J outward and carry in the same direction the upper end of the cutter-shaft disk. The movement of the head-block J moves the cut-terdisks to a proper position as to the width of the stave to be formed. This relation is controlled by diminishing or increasing the radius through which the bar 1 moves by means of its adjustable connection with said block J. Thus the cutter-heads are set automatically by the progress of the stave at the proper width and at the proper angle to cut the bevel of the edge.

Between therear pair of guide-rollers, E E, and the cutter-heads one of the upper feedrollers, X, is mounted in upward-yielding bearin gs it, and it is provided with a cog-gear, it", on one end of its shaft, which shaft and roller is raised when the billet passes under ll hen the said shaft is raised, its cog k mtshes with a cog, k mounted in the frame, which cog is geared through medium of the idler-cogs k with a cog-wheel, it on a shaft, 10, mounted in pivoted frame M, arranged beneath the table, the construction of which will presently be described.

Depending from the shaft X are arms N, the

lower ends of which are rigidly connected to a frame, 0, disposed below the lower section, J, of the head-block J, said block resting upon friction-rollers n. a, jourualed in the frame 0, said section J being provided with a line mesh of teeth j in its upper face, for a purpose presently explained.

From the upper face of the upper sections,

.l, project short piutles 10, which enter diagonal slots 11, formed in the arms 12 of a bell-cranklevcr, l 3, pivoted at ll to theframe.

Arms 15, pivoted at one end to the bell-cranklever arms 16, are pivotally connected at their lower ends to one end of the arms in m of the frame )I, previously referred to, said arms being pivoted at their opposite ends to the frame, as at m.

As before stated, the shaft is is mounted in the frame M and carries a cog-wheel for operating it. It is also provided with two diagonally-arranged cams or disks, P P, which operate within two yokes, Q, Q, formed on the ends of arms Q Q, pivoted, as at q, to the frame and passing one under each of the headblocks, as shown. The arms Q are arranged to be vibrated horizontally by means of the disks P P: Each of these bars is provided with a bearing-box, p p, to receive a projecting stud, p, secured to the under side of each of the lower head-blocks, J for a purpose presently described.

lVithin each of the yokes Q Q project two screw-pins, 18 18, the ends of which are designed to abut or lightly touch the diagonal disks, againstwhich thesaid disks in their rotation act as eccentrics. (See Fig. 8.)

The operation of the machine as the billet passes through the vertical or guide rolls is as follows: hen the billet is about to enter between said rollers, the shafts of which rollers have a pivotal connection at their lower end, their upper ends are spread apart, the degree of such movement depending upon the width of the billet. This movement is communicated through the s Jring-arms, the

rocks-shafts G, and the arms I to the upper head-block sections, J, which have journaled thereto the upper end of the cutter-disk shafts, said shafts swinging in an are from their lower pivotal bearings, thus setting the disks ready to cut at a proper position for the width of the billet to be treated. This transverse movement of the upper section, J, causes the pintle 10 to operate upon the bell-crank lever 13 and cause it to slightly raise the swinging frame M, carrying the diagonally-arranged disks, and properly sets them for operation in the yokes Q. The degree which the said frame M is raised is also determined by the size of the billet. Now at this stage of treatment of the billet it will be observed that the cutter-disks which cut the bevel and the diagonal disks which regulate the bilge of the stave are properly set for operation. The billet then passes under the yielding roller, raises it and the shaft, also raises the lower head-block sections, J into contact with the upper sections, J, by means of the rods N, andat the same time causing its gear 7; to mesh with the gear k and through the intermediate gearing cause the shaft IE6 to revolve. It will be understood that the intermediate gearing is so arranged that but one complete turn of the shaft is will be accomplished durin the passage of the length of the billet past the cutters. The cutters 10w begin to cut the bevel, the proper angle having been given by the movement outward of the upper head-block, J. Now as the billet proceeds the gearing devices from the yielding shaft to the shaft 7; revolve said shaft 75". The diagonal disks operate upon the vibrating arms, their first movement being gradually outward, which arms move both the headblock and the cutters in a similar direction and until the center of the billet is reached, when the diagonal disks begin to slowly draw the arms together and cause the head-blocks and the cutters to have a similar movement, and thereby, while the cutters are making the bevel-cut, also form the bilge at the same time,

said operation of cutting the bevel and making the bilge being done automatically'and by a continuous movement of the billet. To prevent the shaft it from getting a slightly too much turn, which might be caused by the momentum thereof, I provide it with a ratchetwheel, 19, and engage the same with a pawl, 20, which pawl is connected to the shaft X, as shown. By this construction it will be seen that when the passing stave raises said shaft it will draw the pawl 20 out of engagement with said wheel 19, and when the end of the billet passes beyond the small roller 1- the shaft X drops and the pawl will again drop into the wheel, as will be clearly understood from the drawings. To keep the yielding shaft and roller raised after the rear end of the billet has passed from under them until it has been entirely treated by the cutters, I arrange a pivoted frame, R, which is pivoted near one end at 1' and has its short arms 1-. "I" extend under said shaft, while its heavier longer arms, r extend forward and form a bail on which is journaled a small frictionroller, r passes over the roller r it will hold said end down, and the arms 7 1" will support the shaft until tlle billet passes from the roller r which roller is in line with the cutters. The billet passes forward and is passed beneath a concave-facedplaner or cutter, which gives form and finish to the outer convex surface of the stave. It will be understood that the connection between the gear on the shaft is and the intermediate gear is such as to permit of the slight raising or lowering of said shaft without disconnecting said gears. As the contactsu-rfaces of the upper and lower sections, J and J of the head-block J must be such as to permit said sections to mesh at Very short intervals of movement, I form the teeth j j of thin steel-like blades 26, (see Fig. 9,) and set them edgewise in a socket, 27, in the faces of the sections J J and hold them in place by screws 28 and nuts 23, so they may be readily removed for grinding and any wear compensated for by placing beneath them a thin sheet of metal or other desired material. (See Fig. 9.)

From the foregoing description, taken in connection with the drawings, the operation and advantages will be readily understood.
